my truck is throwing a code 42. anyone know whats on that circuit? i replaced the distro with a msd, msd coil, knock sensor, and esc module. what else could it be?
 
i just had a code of 42 a while back it was my ignition control got one at advance auto parts it was i think 35$
 
How is your truck running? Missing/hesatation under load?
Did it set the 42 after you replaced the dist with MSD?
 
ignition control is under the dist cap when i did the paper clip in the computer outlet it threw me a code of 42 which i looked up and told me it was the ignition control. before i changed it i used to get the check engine light on and then it felt like it was running out of gas it was missing so i changed it and all is good now. someone on here showed where to find codes but i dont remember where sorry.
